The intent of this AGARD Report is to: Analyse both current and anticipated requirements for information displays in military avionics. Identify display applications where new technologies in visual displays have the greatest impact on military avionics. Survey the present status and potential for further development of a wide range of modern display technologies. An engineering view on vision and displays explains the technical factors affecting the perception of displayed data, sampling and addressing, the human factors affecting display design and use, and the use of color in displays. A description of technologies includes the cathode ray tube, vacuum-fluorescent tubes, liquid crystal displays, light emitting diodes, electro-luminescent displays, electrochemical displays, and other display technologies. The application of display technologies to military avionics is examined in the areas of classifications, head-up displays, head-down displays, helmet-mounted systems, keyboard displays, and alphanumeric modules. An assessment is made of modern display technology potential. Reference listings resulting from a comprehensive review of recent work in display technologies are also provided.
